Embodiment 2

[0067] On the basis of Embodiment 1, after the texture is displayed on the screen, the following steps are also included for the case where the frame of the animation sequence is multi-frame:

[0068] S401: Determine whether the current frame is the last frame in the sequence of animation frames, if so, then end, if not, then go to step S402;

[0069] S402: Load the next frame, and judge whether the picture of the current frame needs to be replaced with the picture of the next frame, if yes, go to step S403, if not, go to step S404;

[0070] S403: Load the picture corresponding to the next frame, generate a texture from the picture, and set the position and size of the generated texture based on the viewport coordinate system in the VR spherical space according to the texture coordinate information corresponding to the next frame, and then go to step S3;

[0071] S404: According to the texture coordinate information corresponding to the next frame, set the position and size o...

Embodiment 3

[0073] On the basis of Embodiment 1, it also includes parallel loading of animation and UI resources during the startup process of the VR set-top box Launcher. The specific steps are:

[0074] A: After the VR set-top box Launcher is started, the animation is loaded, and during the animation loading process, it is judged whether UI resources need to be loaded. If yes, continue to load the animation. If not, go to step B;

[0075] B: Use multithreading to load the picture of the UI resource, and generate a texture from the picture of the UI resource through the glGenTextures method, and set the transparency of the generated texture to be invisible, and go to step C;

[0076] C: Continue to load animations, after all animations are loaded and played, go to step D;

[0077] D: Set the transparency of the texture of the UI resource image to be visible.

[0078] Start multi-threading to generate textures from high-definition pictures in the UI during the animation loading process. ...

Embodiment 4

[0080] The embodiment of the present invention provides an OpenGL ES-based VR set-top box startup animation production system, including an acquisition module, a generation module, a transformation module and a display module.

[0081] The obtaining module is used to obtain the number of animation sequence frames, the picture information and texture coordinate information corresponding to each frame.

[0082] The generation module is used to load the picture corresponding to the current frame, generate a texture from the picture, and then use the viewport coordinate system in the VR spherical space as a reference to generate the position and size of the texture. The setMatrix4 function uses a 4×4 matrix to transform the spatial position of the texture. The transformation of the spatial position of the texture includes moving, rotating and scaling.

[0083] The transformation module is used to transform the spatial position of the texture through the setMatrix4 function. The ...

Abstract

The invention discloses an OpenGL ES based VR set-top box animation production enabling method and system, and relates to the field of three-dimensional scene building in mobile VR devices. The methodcomprises S1, obtaining the number of animation sequence frames, corresponding picture information of each frame and texture coordinate information; S2, loading a corresponding picture of a current frame and generating a texture by the picture, and generating the position and dimension of the texture by regarding a viewport coordinate system in VR spherical space; S3, transforming the spatial position of the texture by a setMatrix4 function, wherein the setMatrix4 function means that transformation of the spatial position of the texture is carried out by using a 4*4 matrix; and S4, performinginverse transformation on the position and the dimension of the texture which is subjected to the transformation of the spatial position, then transforming the spatial position of the texture into anormalized device coordinate and displaying the texture on a screen. The OpenGL ES based VR set-top box animation production enabling method and system can efficiently solve the problem of fussy computation caused by frequent replacement of the textures in an animation loading process.

Description

technical field [0001] The invention relates to the field of three-dimensional scene construction in mobile VR devices, in particular to an OpenGL ES-based VR set-top box startup animation production method and system. Background technique [0002] Since 2016, VR (Virtual Reality, virtual reality) products have been blowing out, and the VR industry valuation will reach more than 40 billion US dollars in 2020. Virtual reality will be the next general-purpose computer platform after mobile phones. VR set-top box is a new product form, which integrates VR headset, gateway, and Android set-top box, and can meet the needs of users for VR services, OTT (Over The Top, Internet TV) video, large-scale games in the living room, and wireless coverage. Wide application prospects. [0003] The difference between VR applications and ordinary Android applications is that the scenes and graphics of VR applications are in three-dimensional space, so VR applications have higher requirements ...
